easy

Write the formula to find the magnitude of the gravitational force between the earth and an object on the surface of the earth.

Option A

Option B

Option C

Option D

Solution

Let $M_E$ be the mass of the Earth and $m$ be the mass of an object on its surface. If $R$ is the radius of the Earth, then according to the universal law of gravitation, the gravitational force $(F) $ acting between the Earth and the object is given by the relation:

$F=\frac{G M_{E} m}{R^{2}}$
